Abstract

Provided is a high strength hot rolled steel sheet having superior punchability and hole expandability and a tensile strength TS of at least 980 MPa and a manufacturing method for same. The high strength hot rolled steel sheet has a structure with specified amounts of C, Si, Mn, P, S, Al, N, Ti, Cr and B as a component composition and that comprises a main phase that is a bainite phase with an area ratio of at least 85%, a second phase that is a martensite phase or a martensite-austenite mixed phase with an area ratio of at most 15% and a ferrite phase that is the remainder, wherein the average grain size in the second phase is at most 3.0 µm and furthermore, the average aspect ratio of the prior austenite grains is 1.3-5.0 and the area ratio of recrystallized prior austenite grains to unrecrystallized prior austenite grains is at most 15%, and wherein deposits under 20 nm in diameter are at most 0.10 mass%.
